摘要： Provided are an anode active material for a lithium secondary battery, a method of preparing the same, and a lithium secondary battery containing the same. The present invention provides an anode active material for a lithium secondary battery including: a carbon based particle; a first carbon coating layer positioned on the carbon based particle and including pores; a silicon coating layer positioned on the pores and/or a pore-free surface of the first carbon coating layer; and second carbon coating layer positioned on the silicon coating layer, a method of preparing the same, and a lithium secondary battery containing the same.
